Students and faculty involved in the Biogas Energy Project have developed an anaerobic digester that uses bacteria to break down organic matter. During decomposition the matter releases hydrodgen and methane, which can then be used to produce energy.
The team currently receives 8 tons of leftover food scraps weekly from San Francisco area restaurants to produce enough energy to power 10 large homes during that time. Led by Professor Ruihong Zhang, the Biogas team has partnered with a company called Onsite Power Systems, and will operate on a larger scale in coming months as they bring the technology to farms, dairies, and other companies that produce organic waste.
